It's a beauty of a clam too. I need to figure out how to ensure this one stays. I know all the info, just haven't been successful yet.

That's one thing I've never tried to keep. I may look into one now that the euphyllias are gone. Don't starfish eat them or the other way around? I don't think I can part with my red Linkia though it's always in the way when I decide to use the mag-float...

I'm not aware of any stars that eat them...reef safe stars that is. Only issue I've had with them is pyramid snails.

I would be cautious with any stout bodied stars, as they would be the ones most likely to pry a clam open. Chocolate chip stars definitely out of the question, and I imagine any others with the same body style.
The linkia stars may not be powerful enough with just spindly arms to pry a clam open.
But bear in mind, all a starfish has to do is get it open enough to squish his guts in there, and that is not very wide at all, maybe 1/8" or less.
From what I understand they are relentless as well and will keep pressure on a bivalve for hours if needed to exhaust them so they relax just enough.......
think of a boa constrictor in reverse, instead of crushing, its pulling.

+1. Yes..I think this is one of their main predators in the wild. Not sure if linckias can or can't , but I would be concerned. I don't think a serpent can do it though. The star must have those suckers on it's "legs", which serpents do not have.
Per : 10 Facts About Starfish (Sea Stars)

"They prey on bivalves like mussels and clams, as well as small fish, snails, and barnacles. If you've ever tried to pry the shell of a clam or mussel open, you know how difficult it is. Sea stars wrap their arms around the animal's shell and pull it open just enough. And then it does something we could never imagine - it pushes its stomach through its mouth and into the bivalve's shell. It then digests the animal and slides its stomach back into its own body. This unique feeding mechanism allows the sea star to eat larger prey than it would otherwise be able to fit into its tiny mouth."
